System Stability Tester tries to test the system's stability by calculating up to 128 millions of Pi digits.
It supports multiple calculation algorithms. For the moment only two have been implemented. The Quadratic
Convergence of Borwein and Gauss-Legendre, the algorithm SuperPi uses. The testing process includes the
creation of two or more threads. After each step of the calculation, the results of all the threads are compared.
Any differences between them are reported. There is also the option for single threaded calculation, but in this
case there is no stability check
